Racecomp Engineering's goal was to help cure the understeer that adds to lap times at the track and autocross course. Hearing reviews that the Yellow spring traditionally paired with the WRX GTWORX Bilsteins was too harsh for some, a less aggressive performance spring has been produced that retains available bump travel and works in conjunction with the rear motion ratio. The result is a car that handles extremely well from corner entry to corner exit yet retains ride comfort.
These lowering springs do include new front and rear bump stops.
Due to the lower spring rate compared to the Yellows, the RCE Regular Guy springs may be used with stock struts on the 2009+ WRX. However, 2008 WRX owners will need upgraded struts to be able to use these.
